Keyword for the outer class from an anonymous inner class

In the following snippet:

public class a {
    public void otherMethod(){}
    public void doStuff(String str, InnerClass b){}
    public void method(a){
        doStuff("asd",
            new InnerClass(){
                public void innerMethod(){
                    otherMethod();
                }
            }
        );
    }
}

Is there a keyword to refer to the outer class from the inner class? Basically what I want to do is outer.otherMethod(), or something of the like, but can't seem to find anything.
